we all keep observing people’s behavior and we are many a time aware of people’s acceptance level with whom we keep interacting with

now when we find the acceptance level of other’s is low, may be we hold back from sharing it with them . this has happened with me too .

now we also assume things like what would the opposite person reaction may be .

if we feel the reaction may not be in our favor , again we hold back

it might also depend on our acceptance level, when the opposite person’s views are not inline with ours we may not like it sometimes, we may fall into heated up arguments and thus to avoid that we do not open up ourselves with certain people

we may many a times feel, what if my ideas are not convincing enough for others to consider it as a game changing idea

thus we choose a few people where we open up more and share our thoughts.
